Abstract

In some embodiments, a computer-implemented method includes receiving, in a processor, a device description code identifying components of a device and connections between the components, wherein some of the components and connections form boundary cells used for testing the device. The method can include processing, in the processor, the device description code to determine that the components and the connections meet a standard governing components and connections necessary for the boundary cells. The method can also include traversing the connections between the components to determine that the connections meet the standard, and reporting, via one or more output devices, that the device complies with the standard.
